Creator:: Boss, Theodore R. (Theodore Robert)
Abstract:: Vegetation ecology of eight Oregon freshwater wetlands was described and net aerial primary productivity estimated in four wetlands. Plant cover samples were used to classify 37 wetland and 11 terrestrial communities by agglomerative hierarchical clustering. Samples and species were ordinated. Direct measurements were made of sample relative elevation, inundation duration,...

Creator:: Schisler, David Albert
Abstract:: Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...

Abstract:: Sunflower (Helianthus annuus L., cv. NK894) seedlings, grown hydroponically, were exposed to ozone concentrations of 0.0, 0.1, 0.2, and 0.3 ppm at 60% RH, or 0.0 and 0.3 ppm at 30% and 90% RH, for 6 h/d, for four consecutive days, at ages 15 to 18 days from seeding. Plant...

Creator:: Forney, Charles F.
Abstract:: Sinks, plant organs which depend on the import of assimilates for growth, play a central role in determining assimilate distribution patterns within the plant. The strawberry fruit is a strong sink for dry matter and its effect on carbon partitioning and assimilation in the plant as well as the mechanism...

Creator:: Jachetta, John Joseph
Abstract:: Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)- 6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)- glycine], the naturally occurring apoplastic leaf solutes, and the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate) were compared. Aliquots of sap were expressed from intact sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4 bars. Three distinct fractions were detected...

Creator:: Talebbeydokhti, Nasser
Abstract:: Incipient motion of cohesive sediment and the role of flow parameters were investigated for separate and combined unidirectional and oscillatory flows. Sediment from Sturgeon Lake, mainly silt and clay with organic matter, was used as bed material In recirculating and wave flumes. Bench-type experiments indicated that when the submerged sediment...
